Electric connector, charging pile and charging system

Abstract

The embodiment of the invention relates to the technical field of electric energy transmission, in particular to an electric connector, a charging pile and a charging system. The electric connector comprises a shell, a joint and a cooling medium, the shell is provided with an accommodating cavity and two oppositely arranged through holes, and the accommodating cavity is communicated with the outside through the through holes. The connector comprises a first part and second parts, the second parts are arranged at the two ends of the first part, the connector is inserted into the shell, the first part is located in the containing cavity, the second parts penetrate out of the through hole and are exposed out of the outer surface of the shell, and the first part is subjected to insulation treatment and heat conduction treatment. The cooling medium is contained in the containing cavity. Through the above structure, after the first part is subjected to surface treatment, excellent insulation and heat conduction effects can be obtained, so that after the joint generates heat, heat is directly dissipated through a cooling medium. Meanwhile, electric leakage of the connector can be effectively prevented after insulation treatment. Therefore, the transmission efficiency of electric energy is improved.
